Physics
A rabbit is moving in the negative x-direction at 1.10 m/s when it spots a predator and accelerates to a velocity of 13.9 m/s along the negative y-axis, all in 1.20 s. Determine the x-component and the y-component of the rabbit's acceleration. (Enter your answers in m/s2. Indicate the direction with the signs of your answers.) HINT

Explanation:
Initial velocity u = -1.1 i m /s ( along - ve direction )
final velocity = - 13.9 j
change in velocity = -13.9 j + 1.1 i
rate of change of velocity
acceleration
= (-13.9 j + 1.1 i) / 1.2
= -11.58 j + 0.916 i
x component
= 0.916 m /s²
y component
= - 11.58 m / s²
Ответ:
D
Step-by-step explanation:
so total travel by x bikers = 50 multiplied by x = 50x
According to the question
50x = 560
dividing 560 miles by 50 miles per biker give ya 11.2 or approximately 12 bikers.
